Abstract:
Objective To preliminarily investigate the methods,safety and short to medium-term effectiveness of the interventional ultrasound applying in the hybrid procedure to treat the thrombosis of arteriovenous graft(AVG).Methods Twenty patients with the thrombosis of AVG,who received the hybrid procedure defined as Fogarty catheter thrombectomy and percutaneous transluminal angioplasty (PTA) guided by the ultrasonography,were retrospectively investigated. The display effects of the ultrasonography were observed.The technical and clinical success rates were evaluated.All the cases were followed up every 3 months for at least 1 year to evaluate the post-interventional assisted primary patency and the post-interventional secondary patency.Results All the processes were clearly displayed and well guided by the interventional ultrasound during the procedure.The technical and the clinical success rates were both 100%.No major complications were recorded.The post-intervention assisted primary patency rate was 100%,92.9%,85.7%,71 .4% at 3,6,9,12 months,respectively.The post-intervention secondary patency was 100%,100%,89.5%,89.5% at the correspondent months.Conclusions This pilot research shows the hybrid procedure guided by the interventional ultrasound to treat the thrombosis of AVG has high success rate and satisfied patency in short to medium-term.The interventional ultrasound is an effective, safe and convenient guiding method to the hybrid procedure,and has the value for clinical application.
